CONCEALED COMBINATION FAUCETS AND W'ASTE.

Application filed July 3, 1922. Serial No. 572,469.

To all whom it may concern.' Y Be it known that I, WALTER F. HINKLE', a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful VImprovements in Concealed Combination Faucets and lVaste; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the arrangement of the hot and cold water supply faucets and the waste pipe for baths tubs, wash bowls, sinke, etc., and is particularly adapted to meet the requirements of modern plumbing for convenience in use, and attractive appearance, i.v e., absence of all exposed piping and operating connections. This invention consists of a new and useful arrangement 0f the supply pipes and waste or outlet pipe that results'in having only the three valve handles projecting through the wall of the room above the tub or bowl, all the piping and valves being arranged behind the wall.

The primary object of this invention is to produce a simple, neat and compact arrange ment of supply and waste pipes for the purpose indicated above.

It is a further object of this invention to greatly simplify the piping arrangements leading to and from the ixture disclosed herewith, in order to reduce the cost of installation to a minimum consistent with satisfactory operations.

Other and further important objects of this invention will be apparent from the disclosures in the drawings and specification.

The invention (in a preferredy form) is illustrated in the drawings and hereinafter more fully described.

ln the drawings,

Figure 1 is a front elevation of a device embodying this invention.

Figure 2 is a section on the line 2 2 of Figure 1 showing the relative position of this device with regard to a wall and, bathf tub.

Figure 3 is a section on the line {3L-3 of Figure 1 with parts in elevation.

Figure 4 is an enlarged section on the line 4-4'01 Figure 2.

Figure 5 is a rear view of the waste controlling linkage.

As shown on the drawings, the numeral 1 refers to a wall of the bathroom ybehind which the valve mechanisms of this invention are located. A bathtub 2 may be a separate unit or a built-in part of the bathroom as desired, as this invention is equally suited for either type of tub. It is to be understood that this combination fixture has equal advantages for use with wash bowls, sinks and other plumbing fittings of that class, with only the slight constructional variations required by the different uses. A plate 3, arched lat the center to provide a support for a waste valve operating mechanism, is aflixed to the back of the wall 1. The plate 3 carries brackets 4 shown dotted in Fig. 1 through which the hot and cold supply pipes 5 and 6 pass and are clamped therein by set screws 7. The water valves 8 are formed in a T-shape with one branch of the run plugged as at 9 in order toavoid special right and left forms of angle valves and to provide for additional connections to shower fixtures and the like, if desired or necessary. The particular internal construction of the valves is no part of the present invention` and, as many dierent forms are well known, no description thereof is considered necessary. The hot and cold water leads are brought together at a common outlet 10 leading through the wall and overhanging the tub. The particular piping em ployed in the illustrations consists of street elbows 11 in the stems of the valve Ts, close nipples 12 therein, unionsl?) thereon, close nipples 14 therein, and street elbows 15 therein leading to the ends lof the run ot a common lT 16 whose stem is connected by a ongnipple 17 through the wall into the out- Special features of the valve construction mechanism are shown in Figure 3 wherein the valve stem 18 has an integral collar 19 seating in a bushing 2O screwed into the top of the valve body 8 which extends through a hole in the wall. The collar 19 is held in the bushing' 2O by means or' a packing gland 2l and packing' 22. The packing gland 21 serves to retain a finishing' collar or canopy 23 by means of a shoulder 24. The canopy serves to conceal the projecting parts of the valve mechanism and the hole in the wall, giving an attractive finished appearance thereto.

The waste piping layout comprises a drain opening 25 at the lowest point in the tub provided with an apertured strainer 26 having' a threaded nipple integral therewith adapted to' screw into an elbow ittingQT beneath the tub, and a piping connection through the wall to a special by-pass T 2S wherein a waste valve 29 seats in a partition 30 therein when it is desired to' fill the tub. The outlet to the T 28 has both external and internal threads to' enable the use o f a union elbow 3l, as shown, or a straight pipe or common pipe elbow according to the' requirements of the installation. An overfiow outlet 32 is provided for the tub with a suitable fit-ting 33 therefor and a piping connection 34 therefrom through the wall to a special elbow 35. As shown the elbow has a slip joint 36 with the connection 34 to render assembly as easy as possible. A piping connection 3T leads from the elbow 35 to the top of the T 2S which is provided with a similar slip joint 36. As shown in Figure 4, the overflow connection at the top of the T 28 is bypassed around the waste outlet so' that it will not be shut off by the waste valve 29. rIhe operating means for the 'aste valve comprises a handle or hand wheel 38 secured to a shaft 39 journaled in the central arched portion of the plate 3 with a collar 40 thereon retaining the shaft against endwise movement. The shaft 39 is surrounded by a canopy. 23 similar to those used on the valve stems, and retained in place by a bushing` 4l similar in function to the packing' `gland 2l except of course that no packing is required for this shaft. An operating' crank 42 is mounted near the end oit the shaft 39 and connection 43 having a stop projection 44 thereon which adjustably connects the crank to a relatively long` valve rod 45 which is oifset at 45 and which enters the special elbow 35 through ay boss 4G thereon and extends through a stutiing box 4I within the T 28 to the waste valve 29. The connection 43 is bent so that the crank 42 can be carried past top center until said connection strikes the shaft 39 thus holding the valve 29 oit its seat.

As shown in dotted lines in Figure 5, the sto-p projection 44 is adapted to contact the shaft 39 when the valve is moved to seated position, and the spring action of the relatively long rod 45 acts to hold the valve resiliently in such seated position.

This invention provides three similar valve handles for hot water,v waste outlet and cold water, with a tub filler connection common to both the hot and cold water so that the ordinary spraying` attachments may be used therewith when no regular spraying installation has been made. A partial turn of the central handle controls the waste valve through the crank 42 and the valve rod 45. It will be evident that this arrangement is very Convenient and presents an attractive appearance as only the Valve handles and filler pipes are visible, and the openings in the wall are nicely covered by the canopies.

I am aware that numerous details of construction may be varied through a l'wide range without departing from the principles of this invention, and I therefore do not purpose limitingthe patent granted otherwise than necessitated by the prior art.

I cla-im as my invention:

l. A bath-tub iixture adapted to be built into a wall, comprising an arched supporting plate attached to the rear side of the wall, hot and cold water supply valves supported by the ends thereof, operating' means for said valves projecting through the wall, a common outlet connection from said valves also projecting through the wall beneath the arch in said plate, a waste pipe for the bathtub, a waste valve therein located on the rear side of said wall, operating means for said waste valve leading to the arched portion or said supporting plate, and an operating' handle on the arched portion of said supporting plate projectingthrough the wall lor said last mentioned means.

2. In a bathtub fixture, a combined waste valve and overiiow comprising' a passag'ed body having` an inlet for waste water from said bathtub, an outlet tor waste water, a valve controlling said outlet, an inlet. 'for overiow water from the bathtub. a bypass for said overflow water around said valve into the outlet, and crank mechanism for operating said valve having` a limiting stop lor open and closed positions, said stop being' so i'orlned as to allow movement o'l' the crank past dead center to provide a lock i'or both positions oitl the valve.

In testimony whereof I have hereunto subscribed my name in the presence ot two subscribing witnesses.
